Why does print_r output only one element?

Question

PHP

There is a DB with the table orders. I make a request:

$orders_data = mysqli_query($connection, "SELECT * FROM `orders`");

$orders_assoc = mysqli_fetch_assoc($orders_data);

print_r($orders_assoc);

But print_r for some reason displays only the first element from the database, stubbornly ignoring the other two.

Answer 1

And how much should it be, given that mysqli_fetch_assoc gets one row from the fetch result?
